Specification of Letters Patent.

Patented April 27, 1909.

Application fi1ed October 30, 1908. Serial No. 460,255.

To all whom it may concern: 7

' Bc-it known that 1, CHARLES H. SLANKARD, a citizen of the UnitedStates, and resident of Grayville, l/Vhite county, lllinois, haveinvented certain new and useful improvements in Landdiollers, of whichthe following is a specification containing a full, clear, and

exact description, reference being had to the accompanying drawings,forming a partigure 1 is a plan view of a land roller constructed inaccordance with my invention; Fig. 2 is a cross section taken on theline 2-2 of Fig. 1 and Fig. 3 is a vertical section taken on the line3-3 of Fig. 1.

The frame of my improved land roller comprises front and rear timbers 1and 2, end timbers 3, and center timber, which latter is extendedforward from the frame to form a tongue 5, said'tongue supporting theusual double-tree 6. Braces? extend between the rear portion of thetongue 5 and the front timber 1, and fixed to the central portion of thefront timber 1 is an upwardly and rearwardly projecting spring 8, whichcarries a drivers seat 9. on its upper'end, and fixed on the lowerportion of the spring 8 is a foot-rest 10. Y

Arranged for rotation in suitable bearings 11 fixed on the centralportions .of the end timbers 3 and the center timber 4 is 'a pair ofshafts 12, and rigidly fixed on each shaft, adjacent the bearings inwhich it operates, are hubs 13, with which are formed integral spokes1.4, the outer ends of which arejoined by rings or flanges 15, whichprojecttoward one another, and which fit within the endsof a cylindricalroller 16. These rings or flanges- 15 are secured to the roller by boltsor rivets 7 and fitted within each roller 16 adjacent the center thereofis a pair of rings 18, which are held bymeans of bolts or rivets 19, andformed integral with each ring is an inwardly projecting flange 20, andthe space between the two flanges of each roller forms a track for arolling weight 21, in the form of a heavy metal ball. This ball is freeto roll around the inner surface of the roller 16' be tween the flanges20, and the weight of the ball is disposed on the roller-16 in a planebelow the shaft carrying said roller, and as the roller moves forwardthe ball will naturallytravel to the lowermost point on the interior ofthe roller.

I have shown my improved land roller as being provided with two of therollers 16, each mounted on an independently operating shaft, whicharrangement is preferable in asmuch as a roller so constructed can bereadily turned in either direction in a comparatively small spacewithout dragging upon the ground, which latter action would take placeif a single long roller were made use of.

1 A land roller of my improved construction comprises a minimum numberof parts, is of light draft, and the weight of the balls of the tworollers is very evenly distributed upon the ground.

I. claim: The herein described land roller, comprising a rectangularframe, a pair of indopend ent shafts ournalcd for rotation in the frame,

which shafts are in alinement with each other, hubs rigidly fixed to theends of said shafts, spokes integral with the hubs, rings integral withthe outer ends of the spokes, a cylindrical roller fixed to each pair ofrings, rings hired on the interior of each roller, flanges integral withthe last mentioned rings and a ball arranged to move freely on the innersurface of each roller between the pair of flanges therein.

. 1n testimonywhereof, I have signed my 5 name to this specification, inpresence of two subscribing witnesses.
